What does the 'docker network ls' command do?

The 'docker network ls' command is specifically designed to list all Docker networks available in your Docker environment. When this command is executed, it provides a concise overview of the networks that have been created, including their names and IDs, which can be useful for managing container connectivity and organization within the Docker ecosystem. By understanding the networks, you can ascertain how your containers are linked and can communicate with one another.

In contrast, the other options serve different purposes. For instance, commands related to containers generally use 'docker ps' to list active containers, demonstrating a focus on container management rather than network management. Commands for viewing specific details about a network will typically involve 'docker network inspect', while removing a network would utilize 'docker network rm'. Each of these functions is distinct and supports different aspects of container orchestration and networking in Docker.
